Description

Technical Field

[0001] This invention relates to the field of excretion assistance equipment technology, specifically a commode chair. Background Technology

[0002] With traditional commode chairs, users need to use their own strength to get up after using the toilet. However, for users who are weak or unable to stand up, it is difficult to do so on their own. To address this, commode chairs that provide assistance in getting up have been developed.

[0003] For example, the patent with publication number CN218960610U discloses "A toilet chair", which includes a base, a backrest, a seat and a torsion spring. The seat has a toilet groove and is rotatably connected to the base at the end away from the backrest. The torsion spring has two torsion arms, one torsion arm is connected to the base and the other torsion arm is connected to the seat. The torsion spring can drive the seat to rise.

[0004] When in use, the user sits down, causing the torsion spring to twist and deform; when the user stands up, the torsion spring gradually returns to its original position, driving the seat to rise. The seat can then be placed close to the user's buttocks to support the user while standing, thus assisting the user in standing.

[0005] However, for users who are weak and have upper limb disabilities, it is inconvenient for them to wipe their anus after defecation. In the aforementioned commode chairs, the seat is close to the user's buttocks, and the backrest is located behind the user. Both the seat and backrest obstruct the user's view, making it inconvenient for caregivers to help with wiping.

[0006] Therefore, how to assist users in standing while also making it convenient for caregivers to wipe the user's anus is a technical problem that needs to be solved. Summary of the Invention

[0007] The present invention addresses the aforementioned shortcomings of the existing technology by providing a commode chair that not only assists the user in standing but also facilitates caregivers in wiping the user's anus.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A commode chair includes a base, a seat, and a lifting mechanism. The front end of the base is rotatably connected to a horizontal shaft, and a vertical shaft is provided on the horizontal shaft. The axis of the vertical shaft is perpendicular to the axis of the horizontal shaft. The rear end of the base is provided with two guide frames, and a window is provided between the two guide frames. Each guide frame is provided with a guide hole, and the distance between the upper ends of the two guide holes is greater than the distance between the lower ends of the two guide holes. The seat includes two plates, and a commode groove is provided between the two plates. The front ends of the two plates are rotatably connected by a vertical shaft. The rear ends of each plate are provided with a guide rod, and one guide rod is located in a guide hole. The lifting mechanism is used to drive the two guide rods to rise and fall.

[0010] Furthermore, the lifting mechanism includes a crossbeam and a linear drive structure. The crossbeam is vertically slidably connected to the rear sidewalls of the two guide frames. The linear drive structure is connected to the side of the guide frame and is used to drive the crossbeam to move in the vertical direction. The crossbeam is provided with a transverse hole, and both guide rods are provided in the transverse hole.

[0011] Furthermore, each of the two plates is provided with a support rod on the side opposite to each other, with a handrail at the upper end of the support rod and a gripping bar at the front end of each handrail.

[0012] Furthermore, a fixed back plate is rotatably connected to the rear end of each of the two armrests, and a movable back plate is provided between the two fixed back plates. Both the fixed back plate and the movable back plate are arc-shaped plates, and the fixed back plate and the movable back plate are slidably connected.

[0013] Furthermore, the fixed back plate has a sliding cavity inside, and a limiting hole is provided at the top of the fixed back plate. The limiting hole communicates with the sliding cavity, and the movable back plate slides with the sliding cavity. A limiting pin is provided at the top of the movable back plate, and the limiting pin slides with the limiting hole.

[0014] Furthermore, the base has a receiving groove in the middle, which is connected to the toilet bowl. A plastic bag is placed in the receiving groove, and the opening of the plastic bag is fitted onto the top of the base. The seat plate presses against the opening of the plastic bag.

[0015] Furthermore, the base is provided with a hook on its side, and the plastic bag is provided with a handle at its opening, which is hung on the hook.

[0016] Furthermore, both plates have piston chambers inside, and both plates have piston holes at their bottoms that communicate with the piston chambers. Both plates have air holes at their upper ends on the sides that are close to each other, with the air holes facing downwards and communicating with the piston chambers. A piston plate is provided inside the piston chamber, and a piston rod is provided inside the piston hole. The upper end of the piston rod is connected to the piston plate, and the lower end of the piston rod is provided with a stop block that abuts against the top of the base. A spring is fitted on the piston rod, with one end of the spring abutting against the stop block and the other end of the spring abutting against the bottom surface of the plate.

[0017] Furthermore, the top surface of the base is provided with a hidden groove, and the stop block abuts against the bottom of the hidden groove.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In the commode chair of the present invention, the lifting mechanism can drive two panels to move upward, raising the user's buttocks and assisting the user in standing. Furthermore, the window between the two guide frames and the open panels do not obstruct the caregiver's view, facilitating the caregiver's ability to wipe the user's anus from behind. In summary, the commode chair of the present invention not only assists the user in standing but also does not obstruct the view, making it convenient for caregivers to wipe the user's anus. Moreover, the user can remain seated on the panels during wiping, saving the user's energy and improving user comfort.

[0020] 2. In the commode chair of the present invention, the two open panels cause the user's two buttocks to open, exposing the user's anus, which makes it easier for caregivers to wipe the user's anus, allowing for a cleaner wipe and reducing the risk of bacterial infection caused by incomplete wiping.

[0021] 3. The actions of lifting and opening the two plates are performed simultaneously, which helps to improve adjustment efficiency. Furthermore, since both actions are driven by the lifting mechanism, there is no need to set up separate power sources to drive the two plates to lift and open, which helps to save energy.

[0022] 4. During the up-and-down movement of the guide rod, its inclination changes. Therefore, the horizontal hole needs to have sufficient height in the vertical direction to allow for this change in inclination. When the panel falls back onto the base, the guide rod is in a horizontal state. Because the height of the horizontal hole is large enough, the guide rod located within the horizontal hole will sway vertically. In this invention, because the guide hole is inclined, the inclined hole wall can limit the vertical swaying of the guide rod, which helps ensure the stability of the guide rod and, consequently, improves the stability of the panel, thus enhancing the stability and reliability of the commode chair of this invention.

[0023] 5. When the lifting mechanism is used to lift the two panels, the two panels will lift the support rod and the handrail together, which can help the user to hold onto the handrail for support when standing up, making it easier for the user to stand up.

[0024] 6. When the two panels assist the user in standing, the panels are in an inclined state, and the grip bar at the front end of the armrest is perpendicular to the panel. Therefore, the grip bar at the front end of the armrest is more convenient for the user to grasp and use for leverage, making the commode chair of the present invention more convenient to use.

[0025] 7. The design of both fixed and movable back panels allows users to lean against them comfortably during defecation. Furthermore, because the fixed and movable back panels can accommodate the opening and closing of the panels, and can be raised together with the two panels, they prevent the caregiver's view from being obstructed and ensure uninterrupted wiping of the user's anus.

[0026] 8. By attaching a plastic bag to the base, users are allowed to excrete into the plastic bag, making it convenient for caregivers to discard the plastic bag containing excrement, facilitating excrement cleanup, and improving ease of use.

[0027] 9. When the two plates fall back onto the base, they press down on the plastic bag again to prevent it from falling off under the impact of the excrement, thus improving the reliability of the plastic bag in receiving the excrement.

[0028] 10. By attaching the handle of the plastic bag opening to the hook, the risk of the plastic bag falling off can be further reduced, and the reliability of the plastic bag being placed on the base can be further improved.

[0029] 11. By setting a stop block, piston column, piston plate, spring, piston chamber, and piston hole, air in the piston chamber is replenished when the two plates are lifted; when the two plates are lowered, the piston plate pushes the air in the piston chamber out through the air hole, and the airflow from the air hole blows towards the plastic bag, causing the plastic bag to open under the blowing airflow, increasing the distance between the inner wall of the plastic bag and the user, reducing the chance of the user's excrement splashing onto the user's private parts, and improving the comfort of use.

[0030] 12. Because the airflow can open the plastic bag, caregivers do not need to manually open the plastic bag, which can reduce the labor intensity of caregivers.

[0031] 13. The blowing action of the airflow is linked to the lifting action of the plate, eliminating the need for an additional power source to drive the airflow, which helps save energy.

[0032] 14. By setting a hidden groove, when the two panels fall back, the stop block abuts against the bottom of the hidden groove, allowing the bottom of the two panels to fall directly onto the top of the base, which improves the reliability of the panel support and thus improves the reliability of the user sitting on the panel.

[0053] Detailed Implementation

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] Example 1:

[0056] See Figures 15 to 18 A commode chair, comprising a base 1, a seat and a lifting mechanism.

[0057] See Figure 8 and Figure 14 A rotating seat 11 is fixedly installed at the front end of the base 1.

[0058] See Figure 17 A horizontal shaft 111 is rotatably mounted on a rotating seat 11 via bearings, and the horizontal shaft 111 can rotate relative to the rotating seat 11. A vertical shaft 1111 is fixedly mounted on the horizontal shaft 111, and the axial direction of the vertical shaft 1111 is perpendicular to the axial direction of the horizontal shaft 111.

[0059] See Figure 8 and Figure 9 Two guide frames 12 are fixedly installed at the rear end of the base 1. A window 121 is provided between the two guide frames 12. Each guide frame 12 is provided with a guide hole 122. The distance between the upper ends of the two guide holes 122 is greater than the distance between the lower ends of the two guide holes 122.

[0060] See Figure 2 The seat consists of two plates 2. See also Figure 3 A toilet bowl 21 is provided between the two panels 2. See also Figure 1 and Figure 4 The front ends of the two plates 2 are rotatably connected via a vertical shaft 1111. See also... Figure 2 Each of the two plates 2 has a guide rod 22 fixedly installed at its rear end. (See also...) Figure 15 A guide rod 22 is provided in a guide hole 122.

[0061] The lifting mechanism includes a crossbeam 3 and a linear drive structure.

[0062] See Figure 10 Both guide frames 12 have slide rails 123 fixedly installed on their rear side walls. The crossbeam 3 slides vertically with the two slide rails 123, and the crossbeam 3 has transverse holes 31. See also Figure 16Both guide rods 22 are located inside the transverse hole 31.

[0063] A linear drive structure is fixedly installed on the side of the guide frame 12. This linear drive structure drives the crossbeam 3 to move vertically. The linear drive structure can be one of a hydraulic cylinder, a pneumatic cylinder, or an electric actuator. The pneumatic cylinder includes rod-type cylinders and rodless cylinders. In this embodiment 1, see... Figure 8 and Figure 10 Using a rodless cylinder 4 as the linear drive structure, the rodless cylinder 4 has the advantage of saving installation space. The piston 41 in the rodless cylinder 4 is fixedly installed together with the crossbeam 3. When the piston 41 in the rodless cylinder 4 moves up and down, it can drive the crossbeam 3 to move up and down. When using a hydraulic cylinder as the linear drive structure, the cylinder body of the hydraulic cylinder is fixedly installed on the side of the guide frame 12, and the piston rod of the hydraulic cylinder is fixedly installed together with the crossbeam 3. When the piston rod of the hydraulic cylinder extends or retracts, it can drive the crossbeam 3 to move up and down.

[0064] The working principle of this embodiment 1 is as follows:

[0065] (1) When the user defecates, he sits on the two boards 2 and the feces fall through the toilet groove 21 between the two boards 2.

[0066] (2) After defecating, the user remains seated on the two boards 2. Then, the linear drive structure is activated to drive the crossbeam 3 to move upward. The crossbeam 3 supports the two guide rods 22 to move upward. The two guide rods 22 drive the rear ends of the two boards 2 to move upward. The two boards 2 rotate upward around the horizontal axis 111 as the rotation center. The two boards 2 support the user's buttocks and tilt up to help the user gradually stand up.

[0067] At the same time, the two guide rods 22 slide from bottom to top along the guide hole 122 during the upward movement. As the distance between the two guide holes 122 gradually increases from bottom to top, the distance between the two guide rods 22 gradually increases. The two guide rods 22 drive the two plates 2 to rotate and open around the vertical axis 1111 as the rotation center. The two plates 2 drive the user's two buttocks to open, exposing the user's anus.

[0068] The caregiver reaches behind the user, through the window 121 between the two guide frames 12 and the toilet bowl 21 between the two panels 2, to wipe the user's anus. During wiping, the window 121 between the two guide frames 12 and the two open panels 2 do not obstruct the view. Furthermore, the open panels 2 cause the user's buttocks to open, increasing the field of vision and facilitating the caregiver's anal wiping. The user can remain seated on the panels 2 throughout the wiping process, conserving energy and improving comfort.

[0069] (3) When the plate 2 is reset, the linear drive structure drives the crossbeam 3 to move down. The crossbeam 3 drives the two guide rods 22 to move down. The two guide rods 22 drive the two plates 2 to rotate downward around the horizontal axis 111 as the rotation center, so that the two plates 2 fall onto the base 1. At the same time, the two guide rods 22 slide down along the guide hole 122 during the downward movement. Since the distance between the two guide holes 122 gradually decreases from top to bottom, the distance between the two guide rods 22 gradually decreases. The two guide rods 22 drive the two plates 2 to retract around the vertical axis 1111 as the rotation center, thereby realizing the reset of the plate 2.

[0070] Based on the working principle described in Example 1, it can be seen that Example 1 has the following effects:

[0071] First, in the commode chair of this embodiment 1, the lifting mechanism can drive the two panels 2 to move upward, raising the user's buttocks and assisting the user in standing. Furthermore, the window 121 between the two guide frames 12 and the open panels 2 do not obstruct the caregiver's view, facilitating the caregiver to wipe the user's anus from behind. In summary, the commode chair of this embodiment 1 not only assists the user in standing but also does not obstruct the view, making it convenient for caregivers to wipe the user's anus.

[0072] Secondly, in the commode chair of this embodiment 1, the two open panels 2 cause the user's two buttocks to open, exposing the user's anus, which makes it easier for caregivers to wipe the user's anus, allowing for a cleaner wipe and reducing the risk of bacterial infection caused by incomplete wiping.

[0073] Third, the actions of lifting the two plates 2 and opening the two plates 2 are performed simultaneously, which helps to improve the adjustment efficiency; moreover, the actions of lifting the two plates 2 and opening the two plates 2 are driven by the lifting mechanism at the same time, so there is no need to set up separate power sources to drive the two plates 2 to lift and open, which helps to save energy.

[0074] Fourth, the tilt of guide rod 22 changes during its up-and-down movement; therefore, see... Figure 13 The horizontal hole 31 needs to have a sufficient vertical height H to allow the guide rod 22 to change its tilt. When the plate 2 falls back onto the base 1, the guide rod 22 is in a horizontal state. Since the height H of the horizontal hole 31 is large enough, the guide rod 22 located in the horizontal hole 31 will sway vertically. In this embodiment 1, since the guide hole 122 is tilted, the tilted hole wall of the guide hole 122 can limit the swaying of the guide rod 22 in the vertical direction, which is beneficial to ensuring the stability of the guide rod 22, and thus improving the stability of the plate 2, thereby improving the stability and reliability of the commode chair in this embodiment 1.

[0075] Further, see Figure 1 To improve comfort, seat cushions 23 are fixedly installed on the top surface of both panels 2. The seat cushions 23 can be made of latex or sponge.

[0076] Example 2:

[0077] This embodiment 2 is an improvement upon embodiment 1:

[0078] See Figure 1 and Figure 2 Each of the two plates 2 has a support rod 24 fixedly installed on the side opposite to each other, and a handrail 241 is fixedly installed on the upper end of the support rod 24.

[0079] When the lifting mechanism is used to lift the two plates 2, the two plates 2 drive the support rod 24 and the handrail 241 to lift together, which can help the user to hold the handrail 241 for support when standing up, making it easier for the user to stand up.

[0080] See Figure 3 Both handrails 241 have gripping rods 242 fixedly installed at their front ends.

[0081] When the two panels 2 assist the user in standing, the panels 2 are in an inclined state, and the grip bar 242 located at the front end of the armrest 241 is in a perpendicular state to the panel 2. Therefore, the grip bar 242 located at the front end of the armrest 241 is more convenient for the user to grip and use for leverage, making the commode chair of this embodiment 2 more convenient to use.

[0082] See Figure 1 , Figure 2 and Figure 7 Each of the two handrail plates 241 has a pin 243 fixedly mounted at its rear end. A fixed back plate 244 is rotatably mounted on the pin 243. The fixed back plate 244 is an arc-shaped plate, and its concave side faces away from the guide frame 12. The fixed back plate 244 has a sliding cavity 2441 inside, and a limiting hole 2442 at its top, which communicates with the sliding cavity 2441. A movable back plate 245 is provided between the two fixed back plates 244. The movable back plate 245 is also an arc-shaped plate, and its concave side also faces away from the guide frame 12. The movable back plate 245 slides with the sliding cavity 2441, and a limiting pin 2451 is fixedly mounted on its top, which slides with the limiting hole 2442.

[0083] When the two plates 2 lift the patient's buttocks, the two plates 2 also lift the fixed backplate 244 and the movable backplate 245 together. As the two plates 2 are lifted, their rear ends open, causing the two plates 2 to move away from each other. The movable backplate 245 slides outward from the sliding cavity 2441 of the fixed backplate 244, and the limiting pin 2451 slides within the limiting hole 2442. This allows the fixed backplate 244 and the movable backplate 245 to adapt to the opening movement of the rear ends of the two plates 2.

[0084] Conversely, when the two plates 2 fall back onto the base 1, they bring the two fixed back plates 244 and the movable back plate 245 down together. As the plates 2 fall, their rear ends approach each other, causing the fixed back plates 244 to move closer together. The movable back plate 245 slides into the sliding cavity 2441 of the fixed back plate 244, and the limiting pin 2451 slides in the opposite direction within the limiting hole 2442. This allows the fixed back plate 244 and the movable back plate 245 to accommodate the movement of the rear ends of the two plates 2 approaching each other.

[0085] The fixed back panel 244 and the movable back panel 245 are designed to allow users to lean against them during defecation, improving user comfort. Furthermore, because the fixed back panel 244 and the movable back panel 245 can accommodate the opening and closing movements of the two panels 2, and can be raised together with the two panels 2, the fixed back panel 244 and the movable back panel 245 can avoid obstructing the caregiver's view and will not delay the caregiver from wiping the user's anus.

[0086] Example 3:

[0087] This embodiment 3 is an improvement upon embodiment 1:

[0088] See Figure 8 , Figure 11 and Figure 12 The base 1 has a receiving slot 14 in the middle, which communicates with the toilet bowl 21. See also Figure 14 A plastic bag 141 is provided in the receiving slot 14. The opening of the plastic bag 141 is fitted onto the top of the base 1, and the plate 2 presses down on the opening of the plastic bag 141.

[0089] The working principle of this embodiment 3 is as follows:

[0090] (1) When the user needs to defecate, a plastic bag 141 can be placed on the top of the base 1 in advance so that the user can excrete feces or urine into the plastic bag 141.

[0091] (2) When the two boards 2 lift the user's buttocks to help the user stand up, the two boards 2 leave the top of the base 1, so that the boards 2 no longer press down on the opening of the plastic bag 141, making it convenient for caregivers to remove and discard the plastic bag 141. Then, caregivers can put on a new plastic bag 141 for the user to use next time they need to defecate.

[0092] (3) When the two plates 2 fall back onto the base 1, the two plates 2 press down on the plastic bag 141 again to prevent the plastic bag 141 from falling off under the impact of feces or urine, thus improving the reliability of the plastic bag 141 in receiving feces and urine.

[0093] Based on the working principle described above in Embodiment 3, it can be seen that Embodiment 3 has the following effects:

[0094] In this embodiment 3, by placing a plastic bag 141 on the base 1, the user is allowed to excrete into the plastic bag 141, which makes it convenient for caregivers to discard the plastic bag 141 containing excrement, making it easy to clean up the excrement and improving the ease of use.

[0095] Further, see Figure 8 A hook 15 is fixedly installed on the side of the base 1, and a handle is provided at the opening of the plastic bag 141, which is hung on the hook 15.

[0096] By attaching the handle of the plastic bag 141 to the hook 15, the risk of the plastic bag 141 falling off can be further reduced, and the reliability of the plastic bag 141 being placed on the base 1 can be further improved.

[0097] Example 4:

[0098] This embodiment 4 is an improvement upon embodiment 3:

[0099] See Figure 5 and Figure 6 Both plates 2 have piston chambers 25 inside. Both plates 2 have piston holes 26 at their bottom, which communicate with the piston chambers 25. Both plates 2 have vent holes 27 at their upper ends on the sides that are close to each other, with the vent holes 27 facing downwards and communicating with the piston chambers 25.

[0100] See Figure 5 and Figure 6A piston plate 251 is provided inside the piston chamber 25, and the piston plate 251 is slidably engaged with the piston chamber 25. A piston post 261 is fixedly installed at the bottom of the piston plate 251, and the piston post 261 is located inside the piston hole 26, and the piston post 261 is slidably engaged with the piston hole 26. A stop block 2611 is fixedly installed at the bottom of the piston post 261, and the stop block 2611 abuts against the top of the base 1. A spring 2612 is sleeved on the piston post 261, one end of the spring 2612 abuts against the stop block 2611, and the other end of the spring 2612 abuts against the bottom surface of the plate 2.

[0101] The working principle of Example 4 is as follows:

[0102] (1) First, before using the lifting mechanism to drive the two plates 2 to fall back, put a new plastic bag 141 on the top of the base 1.

[0103] Then, the lifting mechanism drives the two plates 2 to fall back. The stop block 2611 under the plate 2 gradually contacts the top of the base 1. The stop block 2611 overcomes the elastic force of the spring 2612 and moves closer to the bottom surface of the plate 2, so that the piston column 261 slides upward in the piston hole 26 and the piston plate 251 slides upward in the piston chamber 25. The piston plate 251 pushes the air in the piston chamber 25 out of the air hole 27. The airflow discharged from the air hole 27 blows towards the plastic bag 141, so that the plastic bag 141 is opened by the airflow.

[0104] When plate 2 falls back to its lowest position, stop block 2611 abuts against the top of base 1, and spring 2612 is in the state of maximum compression.

[0105] (2) When the lifting mechanism drives the two plates 2 to lift, the stop block 2611 under the plate 2 also lifts, and the spring 2612 gradually stretches. As the spring 2612 stretches, the spring 2612 pushes the stop block 2611 away from the bottom surface of the plate 2, so that the piston column 261 slides down in the piston hole 26, and the piston plate 251 slides down in the piston chamber 25. The air pressure in the piston chamber 25 decreases, so that external air enters the piston chamber 25 through the air hole 27, so that when the plate 2 falls down next time, the airflow will be used to open the plastic bag 141.

[0106] When the two panels 2 are raised, caregivers are allowed to discard the plastic bag 141 that is placed on top of the base 1, and caregivers are allowed to place a new plastic bag 141 on top of the base 1.

[0107] Based on the working principle described above in Example 4, it can be seen that Example 4 has the following effects:

[0108] First, by setting up a stop block 2611, piston column 261, piston plate 251, spring 2612, piston chamber 25, and piston hole 26, when the two plates 2 are lifted, the air in the piston chamber 25 is replenished; when the two plates 2 are lowered, the piston plate 251 pushes the air in the piston chamber 25 out through the air hole 27, and the airflow discharged from the air hole 27 blows towards the plastic bag 141, so that the plastic bag 141 is opened under the blowing of the airflow, increasing the distance between the inner wall of the plastic bag 141 and the user, reducing the probability of the user's excrement splashing back onto the user's private parts, and improving the comfort of use.

[0109] Secondly, because the airflow can open the plastic bag 141, caregivers do not need to manually open the plastic bag 141, which can reduce the labor intensity of caregivers.

[0110] Third, the blowing action of the airflow is linked to the lifting action of the plate 2, eliminating the need for an additional power source to drive the airflow, which helps save energy.

[0111] Example 5:

[0112] In embodiment 4, when the plate 2 falls back to the top of the base 1, only the stop block 2611 located below the plate 2 can contact the top of the base 1. The stop block 2611 prevents the bottom of the plate 2 from directly contacting the top of the base 1, so that most of the plate 2 is suspended in the air, and the support effect of the plate 2 needs to be improved.

[0113] In this embodiment 5, see... Figure 8 and Figure 11 The top surface of the base 1 is provided with a hidden groove 13, and the stop block 2611 abuts against the bottom of the hidden groove 13. By setting the hidden groove 13, when the two plates 2 fall back, the stop block 2611 abuts against the bottom of the hidden groove 13, allowing the bottom of the two plates 2 to fall directly onto the top of the base 1, improving the reliability of the support for the plates 2, and thus improving the reliability of the user sitting on the plates 2.

[0114] Furthermore, when the top of the base 1 is fitted with a plastic bag 141, the opening of the plastic bag 141 is covered by the hidden groove 13. When the plate 2 falls back, the stop block 2611 abuts the opening of the plastic bag 141 against the bottom of the hidden groove 13, further reducing the risk of the plastic bag 141 falling off and further improving the stability of the plastic bag 141.

[0115] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
